Tov all 'whom 15 may con/fern.' y

Be it known that l, WILLIAM RALPH SILVERTHORNE, a subject of the' Kingof Great Britain,'and a resident of the village of Shell Brook, theljrovince of Saskatchewan, Canada, have invented certain new and usefulImprovements in Harrow Lifters, of which the following is thespecification. l i

My invention relates to improvements in harrow lifters, and the objectof-r the invention is to devise a simpley and convenient means wherebyany one of the harrow sec 1 and 2 indicate carrier wheels provided' withstud axles 3, each axle being provided with an upwardly verticalextension 4.

The stud axles 3 are connected'together by angle bars 5 and 6 .which areconnected together by plates 7.

8 are standard brackets secured at their foot end as indicated at 9, tothe angle bars 5 and 6, serving also to connect such angle barstogether.

The upper end of each standard bracket 8 is outturned as indicated at10, to form an upper hearing support for the vertical portion 4v of thestud axle 3, the lower end of such vertical portion being permanentlyheld in the cross plates 7, asV clearly indicated in `fig. 2.

The lower portion of the stud axle is provided with an enlargement 11bearing against the lower face of the plates i", a nut 12 being threadedintermediately of the ver tica-l portion 4 against the out-turnedportion of the bracket 8..

By this means, the axles are held permanently in position and fromvertical movement.

13 are arms which'are' secured tothe upper ends of the portiens4 ef the'stud axles 3, such arms exten-ding forwardly and connected together inlproximity toV their forvward ends by a' cross bar 14, suchcross barcarrying-a series of loops or eyelets'f15, for a purpose which' willhereinafter appear.

The' crossv bar 14 is pivotally connected to each arm 13'by a pivot bolt16'.

17 is a transverse bar on which are mounted pulley blocks 18, 19, 20,21, 22, 2323*, 24 and 26 is a draft army which is preferably V shaped inform, the arms of the V being provided with saddle portions 27 extendingover the transverse bar 17, and secured thereto, the extreme ends of thearms extending downwardly, as indicated at 23, to the angle bars 5 and@extending transversely of such bars, as indicated at 29, (Fig. 2), beingsecured thereto by bolts 30 further securing the bars 5and 6 together.

31 are a series of harrow sections connec'ted to the harrow beam 32 towhich the harrows are connected by chains 33 in the usual manner.

34 is a block secured to the beam 32 intermediately of its lengt-h.

35r is a goose neck formed at the apex of the V shaped harrow liftingarm 26, such goose neck depending therefrom and being provided with afoot 36 resting upon theV block 34 and connected thereto by a king bolt37.

x38 and 39v are tie rods having hooks 40 at their upper ends extendingthrough oriii'ces 41 of the arms 13, and at their opposite ends beingprovided with hooks 42 extending' through orifices 43 formed in brackets44 which are pivotally connected, as indicated at 45, to the harrow beam32.

By this means a flexible connection is formed between the ends of thearms 13 and the lha-rrow beam 3.a, permitting the arms 13 to have alimited swinging movement to permit the carrier wheels 1 turning in thedesired direction to follow the harrow.

It will of course be understood that as the barrow is drawn over theground, in

turning, the harrow beam swings horizontally and a pull is exertedeither on one tie rod or the other, which thereby swings the arms 13connected together by the cross bar 14 in the desired direction to turnthe wheels 1 and 2 in unison. Y

46, 47, 48, 49 and 50 are cords or cables, each cord being connected toa harrow section 31. The cord/i6 passes upward over the pulley block 18,and then passes longitudinally of the bar 17 around the pulley block 2Oand through an eye 15, the end of the cord depending and formed into aloop 51. Y

Similarly, the cord 47 is connected to the next harrow section insuccession and passes upward over the pulley block 19, and thentransversely of the machine between-the bar 17 and from thence throughthe next eye 15 in succession, its depending end being also formed intoa loop, as indicated.

The cord 48 passes upward from thethird harrow section in succession,over the pulley block 22 and through the third eye 15, its depending endalso being in loop form.

The cords 49 and 50 pass upward from the 4th and 5th barrow sections andover the pulleys 24 and 25, passing transversely of the machine roundthe pulleys 23 and 23X, through the 4th and 5th eyes 15, the ends beingalso formed with loops.

The loops 51 Iform hand-grips by which the operator seated in the seat52, by pulling upon any one of the cords 46, 47, 48, 49 or canindependently raise any one of the harrow sections 31 so as to free itfrom weeds or any othermatter clogging thereon.

From this description it will be seenthat I have devised a very simpleform of harrow lifter which will be very effective, easily operable, andwhich will follow the harrow in any desired direction.

lhat I claim as my invention is:

1. The combination with a harrow beam, and the harrow sections connectedthereto, of a barrow lifter comprising a follower carriage provided withstud axles, a pair of carrier wheels mounted on the stud axles, atransverse member connecting the axles together, a vertical extension toeach axle, means for turnably mounting each vertical extension on thetransverse member, means connecting the vertical extensions to thebarrow beam whereby the horizontal swing of the harrow beam istransferred to the vertical members to turn them in a correspondingdirection to guide the carrier wheels to track with the harrow.

, 2. The combination with a harrow beam, and the harrow sectionsconnected thereto, ofa harrow lifter followerr carriage comprising apair Vof carrier wheels provided with stud axles, a transverse memberconnecting the axles together, a vertical extension to each axle, meansIfor turnably mounting each vertical extension on the cross member,means connecting the vertical extensions to the barrow beam whereby thehorizontal swingV of the barrow beani is transferred to the verticalmembers'to turn them in a corresponding direction to guide the carrierwheels to track with the harrow, and means whereby the carriage wheelsare turned in unison.

3. The combination with a barrow beam, and the barrow sections connectedthereto, of a harrow lifter follower carriage comprising a pair ofcarrier wheels provided with stud axles, a transverse member connectingthe axles together, `a vertical extension to each axle, means forturnably mounting each vertical extension on the cross member, meansconnecting the vertical extensions to the harrow beam, an arm extendingforwardly from each vertical extension, a cross rod pivotally connectingthe arms together, tie rods extending from eachy arm and crossedintcrmediately of their length and pivotally connected at their oppositeends to the harrow beam, and means connected to each barrow sectionwhereby each harrow section may be independently lifted by the operatorfrom a point behind `the follower carriage.

4. The combination with a harrow beam, and the harrow sections connectedthereto, of a harrow lifter follower carriage comprising a pair ofcarrier wheels provided with stud axles, a transverse member connectingthe axles together, a vertical extension to each axle, means forturnably mounting each vertical extension on the cross member, meansconnecting the vertical extensions to the harrow beam, an arm extendingforwardly from each vertical extension, a cross rod pivotally connectingthe arms together, a series of parallel pull cords guided on cross rod,tie rods extending from each arm and crossed intermediately of theirlength and pivotally connected at their opposite ends to the harrowbeam, a transverse bar member carried by the harrow vbeam arm, andpulley blocks mounted thereon around which the aforesaid pull cordsextend individually from each barrow section.

5. The combination with a harrow beam and the harrow sections connectedthereto, of a barrow lifter follower carriage comprising a pair ofcarrier wheels' provided with stud axles, a transverse member connectingthe axles together, a vertical extension to each axle, means forturnably mounting each verticaly extension on the cross member, meansconnecting the vertical extensions to the harrow beam, anarm extendingforwardly from eachverti'cal extension, a cross rod. pivotallyconnecting the arms together, tie rods extending from each arm "andcrossed intermediately of their length and pivotally connected at theiropposite ends to the harroW beam, a transverse bar member carried by thedraft arm, pulley blocks mounted thereon, a cord ex tending from eachbarrow section and guided by the pulley blocks and extending intransverse series over the bar connecting the arms extending from thevertical extensions of the axle arms, eyes carried by such transversebar through which the cords individually pass, and a loop formed by thedepending portion of each oord to form a hand-grip whereby each oord maybe independently pulled by the operator.
